Add intense, accurate bass to your movies and music
The SW-112 easily fills even a large home theater room with deep bass. Plus, it has a clean, neutral appearance that won't clash with your décor. This powerful, high-output subwoofer uses a 300-watt amplifier to drive a strong-yet-light 12" woofer designed for quick, precise movement. The front slot port helps minimize turbulence for clean sound. And since the port is in the front, you won't hear unwanted "boominess" from sound reverberating off your walls and floor. That means you can place this sub just about anywhere and enjoy punchy low-frequency effects.

Product Highlights:

front slot port for reduced turbulence and flexible installation

300-watt RMS BASH® amplifier (continuous power)

12" front-firing woven fiberglass driver

frequency response 26-120 Hz (±3dB)

variable 50-150 Hz crossover

phase switch

auto on/off

line level/LFE (low frequency effects) input

speaker-level inputs

compatible with the Klipsch WA-2 wireless audio adapter kit for an easy connection to a sound system

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Power LED Indicator: Located on the powered subwoofer's front baffle,
this LED indicates the operating status of the unit's built-in amplifier. The
LED is off when the amplifier is in standby mode and green when the
amplifier is on and receiving a signal.

Rubber Feet: The Klipsch powered subwoofer is equipped with four
integrated rubber feet to help prevent against vibration.

Placement: Klipsch powered subwoofers are designed to reproduce deep
bass and deliver the impact that makes your movies and music come alive.
Typically, optimum performance will result if you place the subwoofer in a
corner of the room on the same wall as your front channel speakers.

Controls

Gain Control: The gain control of the Klipsch SW-112 adjusts
the subwoofer's volume relative to the rest of your home audio system. If the Klipsch powered
subwoofer is connected to the Subwoofer Output (LFE) on your AV receiver, first
set the subwoofer volume level control in the receiver to the "half-way" or the
"0-dB" position. Then increase the gain of the subwoofer until the subwoofer's
volume level matches the output of your main speakers. After this setup is
completed, the volume control of your AV receiver will be the volume control for
both the Klipsch powered subwoofer and your connected loudspeakers.

Lowpass Crossover: The Klipsch SW-112 powered subwoofer
features a variable lowpass crossover which is adjustable from 50-150Hz. The
crossover point chosen determines where low bass frequencies are "handed-off"
from your AV system's loudspeakers to the Klipsch powered subwoofer. Set the
crossover point based on the size of your systems' main left/right speakers. As
a general rule, for larger, floor-standing speakers, set the crossover point
between 50-90Hz. If using small bookshelf or satellite speakers for your mains,
set the crossover point between 90-150Hz. The smaller the speaker, the higher
the setting until the bass frequencies blend well between the loudspeakers and
the Klipsch powered sub. If setting the crossover point in the receiver, turn
the Lowpass Filter knob on the subwoofer to the farthest point right (150Hz).

Phase: The Klipsch SW-112 powered subwoofer has an
adjustable phase control which can be set between 0° and 180°. This control is
used to acoustically match the subwoofer's output to your system's main
speakers. Select a position between 0° and 180°, in which the subwoofer has more
output at your main listening position.

Power Auto/On/Off: The Klipsch powered subwoofer features a
3-way power switch. This is the main AC power switch for the subwoofer. This
switch must be in the "On" position for the subwoofer to operate or the "Auto"
position for the Auto-On feature to function. Set this switch to the "Off"
position if the subwoofer will not be used for an extended period of time. When
this switch is in the "Auto" position, the subwoofer will automatically turn on
when it senses a signal. It will automatically turn off after 20 minutes with no
signal.

Connections

Line-Level Input: The Klipsch SW-112 powered subwoofer is
equipped with a pair of line-level RCA-type inputs. Most of today's AV receivers
have a line-level subwoofer output (LFE) labeled Subwoofer Pre Out, Sub Out, or
SW Out. If your receiver has this output, connect on end of a subwoofer cable to
it and connect the other end of the cable into the powered subwoofer's
line-level input labeled "LEFT/LFE". This connection allows the subwoofer to
operate with both music and surround sound movies. In absence of a subwoofer (LFE)
output on your receiver, as an alternative hookup, you can connect Left & Right
channel pre-amp outputs from a receiver to the "Left/LFE" and "Right" input on
the powered subwoofer.

Speaker-Level Inputs: If your AV receiver does not have an LFE out or
subwoofer preamp output, you can connect the Klipsch subwoofer to the receiver
via speaker-level connection, using the powered subwoofer's 5-way binding posts. Using 16-gauge or larger speaker wire, connect the
Red 'positive' (+) terminal of the AV receiver's Left channel to the Red (+)
terminal of the subwoofer's Left speaker-input channel. Connect the Black
'negative' (-) terminal of the AV receiver's Left channel to the Black (-)
terminal of the subwoofer's Left speaker-input channel. Repeat this procedure
for connecting your AV receiver's Right channel input. The terminals on the AV
receiver used to connect the powered subwoofer will be the same terminals used
to connect the AV receiver to your main speakers.

Note: Take care that no bare wires from any of the connection
touch any other terminals, or each other, as this could damage your
equipment.

WA Port (optional): The Klipsch powered subwoofer is fitted
with a proprietary 4-pin "WA-Port" connector for wireless operation, using
Klipsch's optional WA-2 wireless subwoofer kit (714WA2,
sold separately). The Klipsch WA-2 wireless subwoofer kit consists of two
components; a wireless Transmitter & wireless Receiver. The WA-2 wireless
subwoofer kit makes adding the Klipsch powered subwoofer to your home theater
system much easier, because it replaces the need for a separate subwoofer cable
that traditionally must be connected between the receiver and the powered sub.
Now, you can easily place your powered subwoofer where it both sounds and looks
best in the room since you're not restricted by an audio cable.

Solid Subwoofer

I bought this to replace a Polk PSW505 that had died after a good 7 year run. I thought about getting another 505, since they can be had for about half the price of this, and I had been pretty happy with it for the most part. After reading some of the positive reviews here on the SW112, I decided to take the plunge. Man, what a difference! The bass extension of the Klipsch is an immediate attention getter, and port noise (a problem with the Polk) is nonexistent. I use it in a main family room with a mix of 60/40 music and home theater. It does well with music, but really shines as a HT sub. Having this sub hooked up makes me want to watch more movies than I ever did before. When I upgrade my receiver in the near future I will probably add a second SW112 to take it to another level!

Controlled Thunder

Bought a pair of these to replace some Boston 10" with similar wattage. Boston's developed a rattle and had already been replaced once via warranty. The difference's are quickly apparent and I am completely sold on my choice. Excellent control for music and exceptional depth for lossless blu Ray movie soundtracks. My amplifier has two LFE out connections and I just leave the subs on auto on. The amp gives them anything below 50hz from any source coming through.

Pros:Tremendous depth in 20hz territory
Solid construction and zero noise from subs until needed
Like subtle green led showing through speaker grill
Like the wide bass reflex space - not as chuffy as a port
Bought two to truly cover the room and overcome room acoustics
12" really moves air almost effortlessly
Like subtle black matte finish

Cons:Pretty deep box - measure room corners to make sure it will fit - worth it though

Great sound

Upgraded my small 8" subwoofer with this new 12" subwoofer, and what a major difference. The whole family hears low ends that we didn't hear before, not just with movies but also with regular t.v. commercials and t.v. shows. Would love to add another as my receiver can support two subwoofers,might be too much for the wife.

WOW

This subwoofer is a replacement for an older Klipsch RW-12 and all I can say is wow.It balances with my surround system really well and seems to be a definite step up from the older subwoofer.Glad I made the purchase.

Klipsch SW-112 (x2)

Written By Jim D, Rochester, NY on Thursday, May 22, 2014

I have two of these in my living room and, what can I say? I am a glutton for smooth, clean bass. These subs have performed well over the past three months. I use the auto-on setting and the switching on/off is perfectly silent and seamless. This addition has improved my system 100% - I love it again.

Great Sub

I bought this to upgrade from an older 10" Klipsch sub and although the SW-112 is a 12" sub, the enclosure is roughly the same size as the old 10". I use my home theater for movies, music, tv, and games. So far I have been very happy with the SW-112 and it is still breaking in. A previous review mentioned not having an auto on.... not sure what is going on there, but as long as the toggle switch is set in the middle the sub will turn on automatically when a signal is sent and turns off automatically after several minutes of inactivity.

Pros:Relatively small enclosure for a 12" sub (compared to older SUB-10), strong bass, easy to install

Pretty Nice

I love music, all kinds of music.....The sub sounds great. It feels my living space with plenty of sound & even carries into other rooms as well. I really like the the warmth it brings to overall sound.

Pros:The enclosure looks great, very nice quality & not overwhelming being a 12" sub. With that said, it wouldn't stick out like a sore thumb against decor in the room. It sounds great.

Cons:Sometimes at high volume & super low bass notes you can hear some port noise. I wish it had an auto on signal reference. It would be nice to not have to switch it on & off manually.

Velodyne replacement

Has more power than my old Velodyne. I hope this one lasts longer, the old one didn't make it 5 years! Sound is great, almost too much for my rf-52's. Amp went out on old sub but the speaker was still good. Had to destroy the box to get the sub out... Part of the reason I choose not to got with Velodyne again.

Boom goes the dynamite!

This subwoofer is impressive! I am using it in an approximately 30x30 "great room" and it definitely is up to the task! The sound is being piped in via SONY STR-DN840 and I am definitely pleased. As with any subwoofer, it can sometimes be a little difficult to find the perfect balance between epic bass response in movies , but still be tame enough for music. You just have to play with it a little.

Big Surprise

Written By Kirk D, Albuquerque, NM on Monday, June 17, 2013

I purchased this home subwoofer about a week and a half ago. I was honestly a bit skeptical as I've never really been a fan of Klipsch. Even though Crutchfield generally has good advice on equipment I had to find a place to listen to it first. I heard enough and made my purchase. I honestly have to say that I'm pleasantly surprised and am very pleased thus far. The first thing I noticed was the power it displayed. It beautifully handled the lows in the movie U-571. The torpedo explosions at the beginning of the movie and depth charges literally shook my living room. It's breaking in and is sounding much better every day. It is also quick and can handle my music very well. The intro to the Megadeth song Trust sounds amazing. The kick drums hit without a hint of distortions and punch you in the chest. Then the bass guitar hits even deeper once the song takes off. In my opinion it's a very musical sub. I can't wait for it to break in further. I'm not interested in having a subwoofer shake my house or wake the neighbors but I'm interested in a musical subwoofer that sounds equally good with music and movies. It's powerful enough to feel through the floor through action movies even when only turned 1/3 of the way up on the gain.

Took a chance and WOW!

Decided to take a chance on this sub based on reviews. The JL Audio 12W7 is in my opinion the best sub there is (but so expensive). With that being said, for a fraction of the price the SW-112 comes impressively close and it doesn't need 1500w to do it. This sub plays lower than most other powered subs that I've heard out there, period. But yet it stays tight all the way up to my 80hz crossover point. And the best part is that it does it at extreme levels.

Wow - Keeps getting better and better

Written By Alan P., Greensboro, NC. on Friday, April 19, 2013

I had beed reading all the Great Reviews on the RW-12 (which they don't make anymore) and wanted one. I ran across this SW-112 at a Great price and decided to give it a try. I was not positive that I had made the right choice at first but...... as a couple of weeks passed - now I AM Positive that this IS the Sub I want. It keeps getting better and better everytime I jam on it. Loads of Power and just sounds amazing. Highly Recommend this SW-112!

I Freakin Love It!!!!!

If you love BASS, you will love this powered sub!! I listen to House, Rap, R & B, and all the rest. All you need to do is match the the sub settings to your system, its pretty dam easy. I have 2 Infinity Primus P362 tower speakers, this sub completes the system it gets all the lows that the infinity's can't then SOME!! This shit is quality!! It just seems like every time I turn my system on this thing sounds better and better.

Best Subwoofer I've Ever Owned, By Far

I'm not a prolific review writer, but this is one I wouldn't miss. I went through four (4) other name-brand subwoofers for my home theater system, including good name brand products from Polk Audio & Infinity. They all eventually wound up on Ebay. Used with a Yamaha amplifier, none of them gave me the CLARITY of base that this Klipsch has given me. While admittedly not inexpensive, how much would I have saved had I gone to this unit first? All the other subwoofers gave me earth-shaking, furniture-rattling base, but much of it was a raspy, muddy base at higher base levels. They just couldn't seem to deal with those strong spikes that some movies or music produce at certain times. Ths Klipsch handles it ALL with ease and never chokes during those intense levels. I daresay that the base this unit produces is "beautiful" and greatly enhances my home theater experience. Don't go what I went through over the course of several years. Spend the bit extra now and go for this one first. You'll save money in the long run and will enjoy the beauty a good subwoofer is supposed to produce in the process.

Pros:Good clear base at all levels at all times
No choke points
Has a nice "auto-off" feature with a small green LED on the upper right of the unit that shows through the front mesh cover and turns the unit off after 10 minutes of non use (senses no signal). I love this auto-turnoff feature and the ability to see that it's actually on when being used.

Tuning is Everything

I bought this sub as a replacement for comparable Infinity sub and in my opinion, it's without question a superior sub. I just hope it lasts longer before the amp gives out. It's important to note that it did not reach it's full-acoustical potential until optimally tuned, which took several hours of testing and adjusting while listening to a variety of source material. Probably the most notable difference is that I was able to set my low pass at around 100HZ, whereas I couldn't set it above 50HZ with the Infinity. The Infinity tended to sound somewhat muddy when set any higher, at least to my ears it did. The benefit of a higher loss pass setting is a fuller and more evenly distributed lower frequencies vis-a-vis my bookshelf front and center channel speakers.. (Harmon Kardon AVR 2600 Receiver and Infinity Primus Series Surround Speakers)

KABOOM!!!!!

Written By Anonymous, yonker's NY on Sunday, April 15, 2012

Got this sub a few month's ago already broke it in,the sound's that this sub can make is just OUTSTANDING!!!!..... i have it hooked up to a marantz SR5006 RECEIVER,aswell got 2 pair's of the klipsch's RF-62 II and aso got a CENTER speaker the Klipsch RC-62 II and then for suround sound back's i got the klipsch RS-52 II my system is a 5.1 HT system at the moment ,but soon will be a 7.1 in the summer of 2012 i hope.one this i can say to u about this sw-112 is that it can reallly put a beating on the nabor's at night lol and it made my nabor's dog's bark like crazy aswell as i had cops come to my door because they told me the my nabor's herd gun shot's comeing out of my house ,when really i was only watching a bluray movie transformer's dark of the moon .

Pros:really clear bass
wake's the nabors up
and also can make your parents scream and yell at u lol

my limited knowledge

I did not purchase my system based on my knowledge. The store recommended the components I purchased. I was impressed with the sound and the feel of my system from the start, but never had anything of it's Caliber to compare it to. That is the main reason when my sub-woofer quit, I looked for the exact replacement. Based on what I had, your salesman (Axel) agreed with my choice and I have no regrets other then the new SW-112 is in housing size is a bit smaller and doesn't have the second dummy speaker in rear and doesn't have quite the punch that the original had though the original is no longer made.I love it! And, I really liked dealing with Axel and his professional manner. I also was happy with the delivery time. Thankyou and I look foreword to future dealings with your company and I do and will recommend you to my friends!

Pros:I think I made my pro's in my comments.

Cons:The on/ off switch is on the rear making it a little harder to reach it. Maybe a front switch is possible?
